The significance of biodiversity in ecological systems lies in its ability to enhance ecosystem resilience and functionality. High biodiversity contributes to stability, allowing ecosystems to better withstand environmental changes and disturbances. Each species plays a unique role, promoting various ecological processes such as pollination, soil health, and nutrient cycling. Biodiversity also supports human well-being by providing resources for food, medicine, and ecosystem services. Preserving biodiversity is essential for maintaining ecological balance and ensuring a sustainable future for all living organisms.
